The Theoretical Solving of Intersection Point of the Horizontal and Vertical Gravity Gradients in Order to Estimate the Depth of Causative Source of Gravity Anomaly

The depth of causative source of gravity is one of the most important parameter of gravity investigation. Present study introduces the theoretical solve of the intersection point of the horizontal and vertical gradients of gravity anomaly. Two constants are obtained to estimate the depth of causative source of gravity anomaly, first one is 1.7807 for spherical body and the second is 2.4142 for the horizontal cylinder body. These constants are tested for estimating the depth of three actual cases and good results are obtained. It is believed that the constants derived on theoretical bases are better than those obtained by empirical experimental studies.
